Arena Setup Admin overwriting default setups

Description

I'm not sure if this is a Website or Database issue.
Found this out while working on a TWScript for an arena that already had a (default) script set up (brickman). If you create another script for the arena, it's fine, but if you make a change to it, it will overwrite the (default) script for the arena. (I do have the original default saved, but unless someone knows to do so, these could be pretty easily deleted by accident)
